I dont know why you're being downvoted. I design in autocad, revit, sketchup, visio and inkscape. I do network designs in visio, 3d BIM models in revit, small home stuff in sketchup, presentation graphics and icons in inkscape. I export visio stencils to .dwg format which we then bring into revit and turn into 3D blocks for rack elevations etc... There are so many tools to use.
